| Subject | [PATCH] extcon: usb-gpio: switch to use pm wakeirq apis |
| Message-ID | <rkZAS-7uO-17@gated-at.bofh.it> |
Switch to use PM wakeirq APIs which automates wakeup IRQs
enabling/disabling and so allows to make code simpler.

Unfortunately this simple patch depends on:
"[RFC PATCH] PM / wakeirq: fix wakeirq setting after wakup re-configuration from sysfs"
